UNITED STATES PATENT OFFICE RAY ll. MANSON. OF ELYRIA, OHIO, ASSIGNOR TO THE DEAN ELECTRIC COMPANY, OF ELYRIA, OHIO, A CORPORATION OF OH Specification of Letters Patent.

Patented Dec. 11, 1906.

Original application filed August 3 1904, Serial No. 219,687. Divided and this application filed November 1 1, 1905. Serial Nmzsasao.

To. all whom it may concern:

Be it known that I, RAY H. MANSON, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented a' certain new and useful Improvement in Binding-Posts, of which the following is a specification, reference being had therein to the accom anying drawings.

This application is a ivision of my'copending application for telephone-receiver, filed August 3, 1904, Serial No. 219,567, and the invention relates to the binding-post shown and described therein.

The object of this invention is to provide a binding-post which will be neat and compact in its structure and which may be stamped from a sheet of metal, thus making a very inexpensive construction.

A furtherobject is the provision of means carried by the binding-post itself which prevents it from turning when it is clamped upon the cord-tips.

These and other objects will more fully appear from the following specification, taken in connection with the accompanying drawin s, which illustrate my invention, while the novel features are more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a skeleton view of a receiver as removed from the easing and showing the binding-post secured thereto. Fig. 2 is a front elevation of the binding-post alone, and Fi 3 is a transverse sectional view on line as w of Fig. 2.

Referring more especially to the drawings, 1 represents the permanent magnet, 2 its connecting-bar, and 3 the bridge-block, which is provided with a core of insulating material 4, to which the binding-posts are secured. All of the above is shown and described'in the above-mentioned application.

The binding-post consists of a metal punching, which is bent upon itself at 2 to form opposed flat surfaces 3 and 4, each of which is provided with a pair of parallel indentations 6 and 7, which together form a socket or way 9 for the terminal tip 8 of the cord-circuit. These tips reach the sockets 9, formed by the indentations 6 and 7, through the aperture 10 made in the loop of the bend 2. The bent portions of the binding-clamps are sprung outwardl and are pressed inward to grip the termina tips by the screws 11, which take into the insulating-block 4.

Projecting from the side 3 is a tongue 12,

which is adapted to reach through an aperture formed in the cu shaped member 13, carried on the brid e-b ock 3, where it is usually secured. by so dering or otherwise to a wire of the pole-piece windin s. jections are preferably provided with insulation 14 to prevent contact with adjacent metal members. It will be understood that this ton ue 12 may be secured to the support These proupon which the binding-post is mounted when used for other purposes than that shown in the drawings; but in this instance the projections entering apertures of the cupshaped member 13 serve to steady the binding-clamps from turning when the screws 11 are tightened, as well as to form strong and perfect electrical connections. A curved extension 15 is formed on the side 4, which is adapted to engage the side 3 and limit. the movement thereof.

It is obvious that instead of the screws passing into the insulation shown they'may be fitted with nuts, so that the sides of the binder may be pressed together on the wire terminal. This'a nd other changes in details are the sco )e and purview of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isy 1. The improved binding-post consisting of a flat piece of metal bent upon itself to form two limbs .,an opening through the bend to receive a circuit-terminal and'means to force the two limbs together.

2. A binding-post, comprising a resilient plate bent upon itself, provided with an opening through the bend to admit a conductor-tip and perforated through its ends to receive a clamping-screw for forcing them together, and compressing the sides upon said tip. I

3. A binding-post comprising the following instrumentalities: a plate of resilient metal bent upon itself to form two opposed flat members, one having a reduced extension for a circuit connection, the other having its end turned over to serve as a limiting-stop and means such as a elmnping-scrmv to force against the first, parallel longitudirialridgvs In teslimony \vhercol'l have allixcd my formed on eah member to produce anmtersignature in presence 01 two witnesses. 1
